GCHQ & NSA & Child Porn

You may or may not have seen this news and realised the implicationshttp://www.theguardian.com/world/2014/feb/28/nsa-gchq-webcam-spy-program-senate-investigation

about how the NSA & GCHQ hack webcam feeds from Yahoo and have the capability to hack and have hacked webcams built into yours or your kids devices/computers, but as this system is capable of harvesting images from webcam feeds automatically and knowing the rise of teenage sexting, how do you feel that the liblabcon govt have mandated spooks to basically be exposed to what amounts to child porn images?

I have a probably very stupid and paranoid question but does this mean that the cameras on devices can be hacked when not on an active call? As in, when users aren't aware that anyone can see them etc?

According to the Giardian, this took place between 2008-2010, so it isn't a coalition issue.

No, I'm not surprised that spooks can intercept all ways in which people can communicate. And actually, I want them to be able to - because I don't want terrorists, traffickers etc to have safe places.

Teens who sext are more likely to have problems with their direct peer group, or online groomers, than those concerned with national security (though, I suppose if there were a rogue pervert in their ranks s/he would indeed have amazing tools to satisfy depravities from online material).
